"I told you that the zombie crystal nucleus is useful, have you collected it?"

"Yes, there was a collection at the beginning, it was transparent before, the surface was a little gray, then there were larger collections, and some were colored but not much, and now I have several sacks in my space." Lu Shidong has been collecting since the end of the world, and he has also felt the energy in the crystal nucleus, which is a bit tyrannical.

Lu Shidong heard the warning in Yang Jingrui's video, those tyrannical energies can turn people into zombies, so the survivors in the Kyoto base know that the crystal nucleus can be used as currency.

Lu Shidong has opened a shop in the Kyoto base, which supplies a certain amount of things every day, and the survivors are accustomed to buying them with contribution points, and they can also buy them with crystal nuclei.

Yang Jingrui took out the crystal nuclei she had collected before from the space, these crystal nuclei that she had soaked in spiritual spring water, and handed them to Lu Shidong, "These are the first-level crystal nuclei, you can take a look and feel the energy inside." ”

Lu Shidong took the crystal nucleus in Yang Jingrui's hand, the crystal nucleus was as transparent as a diamond, Lu Shidong had never seen such a clean and translucent crystal nucleus after collecting so many crystal nuclei.

"Why is your crystal nucleus so clean, can this be absorbed now?" Lu Shidong asked as he played with the crystal nucleus he took from Yang Jingrui's hand.

"Dig it out of a zombie's head like you, but I've purified it, and now I can absorb it directly and use it to level up my abilities." Yang Jingrui raised her eyebrows at Lu Shidong.

"Well, how do you purify, you have this ability?"

"No, but I can purify, you come to purify and receive two percent as a reward, and other bases or other families will receive forty percent, only through the hands of the Lu family." Yang Jingrui said.

"Yes, I have a few bags here, you can help me purify it first, and then teach me how to use it." Lu Shidong released a few sacks of crystal nuclei in the space.

"Well, yes, after this crystal nucleus is purified, there is still a certain chance that it can activate the ability." Lu Shidong heard Yang Jingrui say that he could activate the ability, and his eyes suddenly lit up, if the ability could be activated, then his army could be stronger.

"Take the crystal nucleus in your hand, feel the energy in the crystal nucleus carefully, and then use the ability to guide this energy back to the body with the ability." Yang Jingrui took a purified crystal nucleus and put it in her hand, and in less than two minutes, the crystal nucleus turned into a small pile of gray-white powder.

Lu Shidong also learned that she took one and put it in her hand, and tried to feel it with her spiritual ability, the first time she felt it, she couldn't guide it, and the second time it took five minutes to successfully absorb the crystal nucleus.

After that, Lu Shidong continued to absorb the dozens of crystal nuclei that Yang Jingrui had grabbed one after another, and felt that the abilities in his body had increased a lot, and Lu Shidong felt that he had reached the third-order level, and if he absorbed one or two more, he should have advanced.

Yang Jingrui also felt the fluctuation of the ability in the air, reached out and took a first-order white crystal nucleus from the purified crystal nucleus in the space, and handed it to Lu Shidong.

"If you absorb this, you should be able to advance to the next level."

Lu Shidong didn't say anything, just took the crystal nucleus in Yang Jingrui's hand and took a look, this crystal nucleus was twice as big as the white nucleus he had absorbed just now, this should be the crystal nucleus of those first-order zombies.

After absorbing the crystal nucleus, Lu Shidong began to advance to the ranks, and Yang Jingrui sat quietly next to him, releasing a trace of mental power while reading a book, in case someone accidentally disturbed him.

Because Lu Shidong absorbed the crystal nucleus for the first time, the effect would be better, and he was quickly promoted.
